Description
Technical field
The utility model belongs to evaporator device technical field, is heated evenly more particularly to one kind, and evaporation intensity is big, prevents
The only luwa evaporator of coking.
Background technique
The full name of thin film evaporator is mechanical agitation type thin film evaporator, also known as thinfilm rotary evaporator.It is a kind of
New and effective energy saving falling film evaporator.The range of viscosities that it is higher with equipment heat transfer coefficient, residence time of material is shorter, applicable
The superior performances such as wide, operation elasticity is big, obtain widely in industries such as chlor-alkali, chemical industry, light industry, food, pharmacy and environmental protection
Using.
Its working principles are as follows: material, which enters after evaporator, forces film forming, heat from heat source by the agitation of rotor upper scraping plate
Heat exchange is carried out through barrel and feed liquid, liquid film boiling is discharged after catching drop of the diaphragm except deentrainment after secondary steam vaporization,
Concentrate is released by bottom discharge port.Therefore thin film evaporator has the following characteristics that
With very high heat transfer coefficient, evaporation intensity is big, 50 is reached to water and organic solvent (viscosity is less than 100cp) etc.~
300kg/m2.h。
Low-temperature evaporation: since thin film evaporator operates under vacuum, vacuum level requirements are determined according to evaporation material properties, greatly
The boiling point of processing material is reduced greatly, therefore is particularly suitable for the low temperature concentration of heat sensitive material.Common material can be selected simultaneously
To handle the concentration to strong corrosive medium.
Residence time is short: material residence time in equipment is shorter, between more than ten seconds~tens seconds.Residence time with
Hanging plate surface groove inclination angle is different and changes.Material is helically lowered away from heating under the push effect of hanging plate in equipment
Cylinder, material are squeezed out, and the residence time is shortened, it is possible to reduce decomposition or polymerization of the product in evaporation process improve solvent
The rate of recovery.
It is energy saving: due to using vacuumizing, material boiling point is reduced, it, can be under the premise of guaranteeing the identical temperature difference
Using low-grade steam, the energy has been saved.The end effect of particularly suitable multiple-effect evaporation is evaporated.
It is easy to operate, it for ease of maintenaince maintains: since rotor-support-foundation system has good stirring action, equipment surface to evaporation material
With the smallest surface scale, it is capable of handling high viscosity, containing particle, thermal sensitivity and the easy medium that crystallizes.
But luwa evaporator feeding manner in the prior art, frequently with top feed, material flows downward from top,
Causing material to concentrate on, top heated time is longer, and material is easy dry and hard.And the type of flow of material from the top down can also be made
At the uneven of each spot temperature of evaporator, the loss of thermal energy is caused.
Summary of the invention
The utility model aim is the defect uneven, easily dry and hard for the heating of existing luwa evaporator, provides one
Kind is heated evenly, and residence time of material is shorter, evaporation intensity is big, the luwa evaporator of slagging prevention.
The utility model to achieve the above object, adopts the following technical scheme that
A kind of luwa evaporator, including evaporation cylinder, the setting of motor driven rotation is in the intracorporal transmission of the evaporative cylinder
Axis, scraper plate, the scraper plate are connected on the transmission shaft by scraper plate support, it is characterised in that: different in the evaporative cylinder body
Position is provided with multiple feed distributors, and material sprays to the evaporation cylinder inboard wall through multiple feed distributors.
It is further characterized by: multiple feed distributor settings are again on the transmission shaft；The transmission shaft and into
Expect that distributor is hollow, and is interconnected, cavity of the material through the transmission shaft and feed distributor, from the one of feed distributor
End sprays to the evaporation cylinder inboard wall.
It is further: the feed distributor interval setting.
Further: material inlet is located at the evaporation cylinder lower part, is connected with the bottom of the transmission shaft.
Preferred: the material inlet is connected with the transmission shaft by rotary joint.
It is further: to be provided with umbrella shape distributor below each feed distributor.
Preferred: the umbrella shape distributor is two, is separately positioned in the scraper plate support below the feed distributor.
The umbrella shape distributor of adjacent two mutually staggers.
Demister is provided with above the transmission shaft.
Filler and collecting tank are provided with below the demister.
There are multiple heating agent collets on the evaporation cylinder.
The utility model material by hollow transmission shaft and feed distributor be used as material channel, material from evaporate cylinder
Different location spray so that offers of material no longer concentrates on evaporating the top of cylinder, material more uniformly spread, and material stops
The time stayed also effectively shortens, slagging prevention.And the heating agent collet of different location respectively corresponds the material spout of different location, makes
The load for obtaining each heating agent collet is more average, to guarantee the uniformity of the temperature of the evaporation each position of cylinder, effectively saves
The about consumption of the energy, improves the evaporation efficiency and production capacity of equipment.
